You can't access the Result variable inside like that. You need a accessor
method to do it for you like this...
Key5Solver>>result
^ Result
But also, you never set the value of Result, see below...

Thats good. Actually I amend my suggestion from yesterday. An instance
variable would do.
I've renamed your method here...

self inform: 'Mining calculation is complete. You can now ask

With the above, in Playground you can do...
solver := Key5Solver new startCalculation . "<<<evaluate this line only"
"wait for information message to appear"
solver result inspect "<<<<now you can evaluate this line to get the
answer"
